[SOLVED] Sound lost. Please help with debug

allbluedream · 2009-01-17 02:04:02

I hate the sound issue since I am terrible at understanding its complexity. But today the problem crawled back to me anyway.

Upgrade the kernel as well as pulseaudio yesterday. All was working well then, but upon bootup today I lost sound--any sound. No error feedbacks, cuz everything seems to be working fine. MPD plays, pulseaudio device chooser sees the output stream, the device, and all. I tried to find if I accidentally muted any channels, but amixer and alsamixer gave no hints on this.

Please help with at least where I can start debugging.

I'm having sound issues since the last kernel update too. However, my problem is mostly with microphone input. What output do you get by running "lspci|grep audio" ? I get this, for example:

[zauber@myhost ~]$ lspci | grep Audio
00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
01:00.1 Audio device: ATI Technologies Inc Radeon HD 3870 Audio device

Same problem here. After upgrade I found I got a new soundcard (snd_pcsp). Blacklisting the module helped.

Thanks! Got my sound back again finally.

Falcata,
Not sure if we were experiencing the same problem, but thanks anyway!

I tried this solution, and started getting random crashes with the sound server :-/

Guess I'm having a different problem

Not having snd_pcsp disabled actually worked for me before, it was the default device after setting up pulseaudio on my box (almost started laughing when the internal speakers started pumping out hardcore techno from mpd).

After the updates and a reboot audio stopped working over here too, and with no errors at all I checked the volume with alsamixer, and PCM was down at zero. A classic. However, it didn't help to increase its volume, nothing I tried worked, and the "solution" from this thread didn't help either.

Many reboots later I launched gnome-alsamixer and saw that the PCM channel was muted, haha. I'd probably forgotten that MM means muted. Posting in case someone else suffered the same problem as I did.
